The breaker will trip at the amperage notated on the breaker. If it's 100A...it will trip at or around 100A. It does not matter if that breaker is physically tied to another 100A breaker.
To understand this, imagine that you remove the mechanical tie from the two-pole breaker. Now you just have two 100A breakers. In actuality, you always had two 100A breakers. The mechanical tie does not change that.
If you then powered two, separate 120 volt devices from the two breakers, each breaker would allow 100 amperes to pass to each of the devices before tripping.
So why are they tied together? That is done when the two-pole breaker is to be used to power a 240 volt circuit. In AC current, electricity flows in both directions. In a 120 volt circuit, it flows "out" toward the device via the hot (generally the black wire) and "back" via the neutral (generally the white wire). Then the cycle reverses. It does this 60 times per second (60Hz). The amperage in the hot and neutral wires are the same (in the perfect world). Only the hot wire is connected to the breaker.
In a 240 volt circuit, there is no neutral wire. You are using two "legs" of 120 volts each that are 180 degrees out of phase with each other. In other words, as leg 1 is flowing "out", leg 2 is flowing "back". Because they are out of phase, the potential difference is twice the voltage of each line or 240 volts. The current flows out and back at the same 60 Hz but this time via the two hot wires (generally black and red). Each of these hot wires are connected to the two terminals of the two-pole breaker.
Due to mechanical tolerances, one breaker will most likely trip before the other. Therefore, if the rated current, (100 amps), is exceeded on either breaker, that breaker will trip and the other breaker will trip via the mechanical tie. This ensures that all power to the outlet is disconnected. If you removed the tie and only one breaker tripped, there would still be 120 volts connected to the outlet.
In summary, each leg of a single, double (2 phase) or triple (3 phase) breaker is capable of allowing the amount of current denoted on the breaker. The connected circuit, regardless of voltage is protected from exceeding that amperage.
The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.
A breaker is based on the amperage that is drawn by the pump motor load. Find the full load amperage of the motor. The wire fed from the breaker has to be rated at 125% of the motors full load amperage. The breaker for motors have to be over sized, usually 250% of the motors full load amps.
breakers are rated by wire size, not voltage. the appliance manufacturer will probably specify amperage.
A 20 amp breaker will trip if the current exceeds 20 amps for an extended period of time. It is designed to protect the circuit from overheating and causing a fire hazard. So, it would take more than 20 amps to trip a 20 amp breaker.
Yes, you can use a 25 amp double pole breaker for a 240 volt heavy duty Whirlpool dryer. It is important to match the breaker size with the electrical requirements of the appliance to ensure proper function and safety.
The maximum amperage capacity of a Siemens breaker rated at 200 amps is 200 amps.
To calculate the total amps in a breaker panel, add up the amperage ratings of all the individual circuit breakers in the panel. This total amperage should not exceed the panel's maximum capacity, which is typically labeled on the panel itself.
The maximum amperage capacity of a 240 amp breaker is 240 amps.
The maximum amperage capacity of a 30 amp breaker is 30 amps.
The recommended amperage for a 30 amp RV breaker is 30 amps.
The recommended amperage for a circuit protected by a 50-amp breaker is 80 of the breaker's rating, which is 40 amps.
The maximum amperage capacity of a 100 amp Pushmatic breaker is 100 amps.
The maximum amperage capacity of a 150 amp circuit breaker is 150 amps.
The maximum amperage capacity of a 20 amp breaker box is 20 amps.
The maximum amperage capacity of a 20 amp mini breaker is 20 amps.
